摘要: To address the climate change caused by anthropogenic emissions of greenhouse gases into atmosphere, it is essential to understand and quantitatively elucidate their cycling on Earth's surface. This paper first presents an overview global three gases, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), followed a description variations in atmosphere. then recent budgets these estimated using two different approaches, top-down bottom-up. Discussions our current knowledge regarding are also presented.
